Allegro MicroSystems, a designer of magnetic sensor and analog power semiconductors, has become a key beneficiary of rising demand in electric vehicles, advanced driver-assistance systems, and artificial intelligence data-center infrastructure. Its fiscal second-quarter 2027 report, covering the period ended September 25, 2026, marked the company's seventh consecutive quarter of sequential sales growth. Investors have been watching closely to see whether that momentum can continue as the company scales its higher-margin data-center and industrial businesses while managing automotive inventory dynamics and margin expansion. The results provided fresh evidence on both the durability of demand and the company's ability to convert revenue growth into stronger profitability.
Allegro delivered second-quarter fiscal 2027 net sales of $276.9 million, an increase of 29% from $214.3 million in the prior-year period and above consensus expectations of roughly $270.8 million. Non-GAAP (adjusted) earnings per share came in at $0.26, doubling from $0.13 a year ago, while GAAP (Generally Accepted Accounting Principles) diluted EPS rose to $0.12 from $0.03.
Non-GAAP gross margin expanded 190 basis points year over year to 51.5%, supported by operating leverage. Automotive sales grew 11% year over year to $173 million, while industrial and other sales surged 79% to a record $104 million. Data center revenue reached a record $46 million, up more than 150% year over year, and management reiterated expectations to more than double data-center sales in fiscal 2027. For the third quarter, the company guided to revenue of $278 million to $288 million and non-GAAP EPS of $0.25 to $0.29.

Despite a clear top- and bottom-line beat, market coverage indicated that Allegro shares came under pressure in the immediate aftermath of the report, suggesting investors had priced in strong execution ahead of the release. The report reinforced a constructive narrative: record data-center sales, a first-ever quarter above $100 million in industrial and other revenue, and sharply higher bookings and design wins. Still, the tempered initial reaction reflects elevated expectations and a degree of caution around valuation and the timing of certain larger data-center program ramps that were pushed out by one or two quarters. Management described those delays as timing-related, with programs still expected to ramp in the near future.
Allegro's forward guidance points to continued growth, with third-quarter revenue expected between $278 million and $288 million and non-GAAP EPS between $0.25 and $0.29. Management also cited a robust backlog and strengthening demand signals as evidence supporting its target of mid-teens annual sales growth over time.
Investors should monitor several key factors in the quarters ahead. First, the pace of data-center adoption remains central, particularly given the timing shifts in larger 800-volt hyperscaler programs. Second, automotive inventory levels and any signs of restocking will be important, since management noted customer inventories remain lean. Third, margin progression toward the company's long-term target of above 55% gross margin will hinge on manufacturing cost reductions, pricing actions, and product mix.
Finally, the company's growing exposure to electrified vehicles, advanced driver-assistance systems, robotics, and energy infrastructure broadens its addressable market, but also ties its trajectory to the health of those end markets. While the reported results were strong, near-term sentiment may remain sensitive to the pace at which recently won designs convert into shipped revenue.
